Abstract

An electrical supply circuit comprises a switching transistor (T1) and a forced control switch (ZS) to control the transistor input. An oscillating circuit (OS) is activated at the beginning of operation and serves to amplify the control switch for the time of operation and oversee the control input of the transistor. An Independent claim is also included for an electrical circuit for a lamp as above.
